To rtll whom it may concern.-

Be it known that 1, JAMES W. BOYLE, a citizen of the United States, and resident of Unity Station, in the county ofAllegheny and State of Pennsylvania, have invented a new and Improved Regulator or Governor, of which the following is a full, clear, and exact description.

The invention relates especially to means for regulating or governing the speed of movement of machinery. To this end the apparatus comprises a casing or stator having a rotor with a piston-like part adapted to run therein. The casing is provided with means for priming it with oil or other fluid, and the ends of the chamber within the shell are con-' nected to permit the fluid to flow outside of the chamber from one end to the other, and at this point the apparatus is provided with means for throttling the fluid-flow, so that by adjusting the throttling means the amount of fluid moving through the apparatus, and consequently the speed of the piston, may be regulated. By connecting the piston with the moving part in connection with which my invention is used the speed of the moving part may be governed or controlled.

The invention resides in certain novel features of construction and organization, which will be fully set forth hereinafter, and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, which show the preferred em bodiment of my invention, in which drawings like characters of reference indicate like parts in the several views, and in which- Figure 1 is a side elevation of the apparatus. i Fig. 2 is an elevational view showing the inner side of one section of the casing or stator and the rotor with its piston-blades in position. Fig. 3 is an elevational view of one section of the stator, showing the chamber therein, inlet and outlet openings, and the priming devices. Fig. 4 is a detail section on the line 1 of Fig. 5, showing the by-pass and throttling devices. Fig. 5 is a vertical section of the apparatus. Fig. 6 is a detail sec tion on the line 6 6 of Fig. 5, this View also showing the by-pass and throttling devices; and Fig. 7 is a developed view of the peripheral cam devices on the stator by means of which the piston-blades of the rotor are actuated.

The stator is mounted on a suitable base 10, and as here shown comprises two side sections 11 and 12, suitably fastened together and pro- 1 vided interiorly with matching grooves 14 and 15, which jointly form an arc-shaped chamber within the stator, the ends of said chamber being separated by walls 16 and 17. (Shown best in Figs. 3 and 5.)

18 (see Fig. 1) indicates a supply-pipe, by means of which the chamber of the stator may be primed. Said pipe communicates with passages 19 and 20 in the wall 17, the passages loading, respectively, to the ends of the cham ber of the stator.

21 and 22 indicate check-valves commanding the passages 19 and 20.

As best shown in Fig. 3, the chamber of the stator is formed with ports 23 and 24, passing transversely from the chamber to the outside of the stator. A central shaft 25 (see Fig. 5) is revolubly mounted in the stator and carries a disk 26, which constitutes the rotor of the apparatus. The rotor is arranged to run freely within the space between the sections 11 and 12 of the stator, and its periphery is flanged, as indicated at 27, so as to form a tight connection with the stator at this point.

28 indicates packing of any suitable sort, which is applied to both sections of the stator and engaged \fith the sides of the rotor to form a fluid-tight connection, enabling the rotor to run freely in the stator without leakage. As shown best in Fig. 2, the rotor 26 is formed with openings 29. These openings are preferably three in number, and as here shown are circular in form. Each opening carries a circular piston-blade 30, said blades being pivoted therein on radial shafts 31. The shafts 31 project beyond the periphery of the stator. (See Figs. 2 and 5.) Each shaft carries at its outer end two fixed fingers 32 and 33, disposed in cruciform relation and lying one outward of the plane of the other. These fingers 32 and 33 are adapted to run around the outer periphery of the stator, and the stator is provided with guides 34 and 35. These guides act on the fingers 32 and 33 automatically to turn the piston-blades 30, so that said blades when running in the chamber of the stator will lie in a plane at right angles to the plane of the rotor, thus engaging the inner walls of said chamber, and when the blades approach the walls 16 and 17 they will be turned to lie in the plane of the rotor, thus permitting the blades to run freely past the walls.

Fig. 2 shows two of the piston-blades in operative position within the chamber of the stator, and one of the blades lying in the plane of the rotor to pass the walls 16 and 17. Fig. 7, showing a developed View of the guide 34 and 35, illustrates the action of these guides on the fingers 32 and 33 automatically to shift the piston-blades in the manner described. Said blades move bodily with the rotor and have an independent movement, turning them into the chamber as they leave the walls 16 and 17 and turning ,them out of the chamber as the blades approach said walls. The result of this operation is that the fluid in the chamber will be caused to circulate out of one of the by-pass ports of the statorfor example, the port 24and back into the chamber of the stator through the other by-pass port, for instance, 23. The guides 34 and 35 are formed around the periphery of the stator, as shown in Figs. 1 and 2. 11 and 12 indicate extensions from the sections of the stator by means of which said sections may be bolted together, the fingers 32 and 33 running under said extensions, as shown in Fig. 5.

As shown in Fig. 4, pipes 36 and 37 communicate, respectively, with the by-pass ports 23 and 24 and lead into the chamber 38. As best shown in Fig. 6, said chamber receives the pipes 36 and 37 respectively, in its end portions, and the chamber is provided with a by-pass pipe 39,-which connects said end portions with the chamber, so that normally the fluid from the chamber'of the stator is free to flow unrestrained through the pipes 36 and 37, the ends of the chamber 38 and the bypass pipe 39. Said chamber 38 is, however, provided with throttling-valves 40, (see Figs. 4 and 6,) these valves being movable back and forth across the ends of the by-pass pipe 39, so as to regulate the amount of-fluid passing this pipe. The by-pass valves 40 are in the form of sliding plates and are connected, respectively, to stems 41. These stems project from the valves in opposite directions and are connected to followers 42. followers are pressed in opposite directions by means of springs 43, so that said springs serve normally to hold the throttling-valves 40 in open position. Connected to the followers 42 are rods 44, (see Fig. 6,) and these rods pass loosely through guides 45, connected, respectively, to the ends of the chamber 38 outside of the same.

46 indicates thumb-nuts, which are threaded on the rods, and by means of these devices the positions of the followers 42 may be changed so as to move the valves 40 into any desired position independently of the action of the springs 43. In this manner the passage provided for the fluid passing through the chamber 38 may be enlarged or diminished at will, and the resistance to the movement of this fluid varied accordingly.

In the practical embodiment of my invention the shaft 25 is connected with the moving part to be governed or controlled, and its connection may be eflected in any desired way. Figs. 1 and 5 indicate a-gear 47, attached to the shaft and meshed with a gear 48 on the shaft, drum, or other rotating part 49 of the apparatus in connection with which my invention is employed. Upon the operation of said apparatus, in connection with which the invention is employed, the rotor is caused to operate in unison with said apparatus, and the piston-blades 30 act on the fluid in the chamber of the stator before described, continuously displacing this fluid from one end of said chamber and said fluid being continuously received at the otherend. This constant circulation of the fluid in and out of the chamber of the stator is made possible by the by-pass communications 36, 37, 38, and 39, and said circulation may be throttled to any desired extent by adjusting the valves 40, as before explained, so that when the speed of the driving part 49 (referring to Fig. 1) exceeds that at which it is set to run the valves 40 will throttle the flow of fluid from the chamber of the stator, and thus arrest or retard the driving part.

The invention is useful 1n connection with all classes of machinery for the purpose explained, particularly for elevators, inclined railways, oil or gas well machinery, vehicles, and the like. Fluid of any sort may be employed in connection with the apparatus. Oil is preferable; but an elastic fluid, such as air, may be employed, if desired.

Various changes in the form, proportions,- and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the terms of my claims.

Having thus described the preferred form of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a chambered stator, a rotor running therein and including a piston-like part adapted to displace fluid from the stator, means forming a by-pass connecting the receiving and discharge ports of the stator, two throttling-valves interposed in said by-pass for the purpose specified, and means for operating said valves.
